Abstract
Description
Technical Field
[0001] This invention relates to a water collection device for water treatment. Background Technology
[0002] Wastewater treatment is divided into categories such as industrial wastewater, agricultural wastewater, medical wastewater, and domestic wastewater. Wastewater has a complex composition, containing various inorganic and organic pollutants, which directly endanger the aquatic environment and human health. In the context of water scarcity, water quality testing and water treatment process debugging rely on accurate and convenient underwater water sampling.
[0003] The existing wastewater treatment sampling device in patent CN211179121U relies on a ground-based telescopic frame and ropes to lower the collection box. While the device has a high degree of integration, it has significant drawbacks: the entire sampling mechanism is assembled as a single unit, making it impossible to quickly separate the water sample storage component from the power supply component after sampling. The processes for water sample transfer, equipment replacement, and internal component maintenance and disassembly are cumbersome. The device is also bulky and unsuitable for narrow pools or deep-water long-distance lowering scenarios. Furthermore, it relies on an external frame to drive the rope lifting and lowering, which limits on-site deployment and prevents independent underwater sampling without external auxiliary equipment.
[0004] Meanwhile, traditional underwater water samplers mostly use manual squeezing airbags and counterweight sinking cylinder structures, which are difficult to operate manually underwater, and the squeezing force of the airbags and the amount of water absorbed cannot be accurately controlled. On the other hand, the airbags, liquid suction pipes, power motors and batteries of electric sampling mechanisms are integrated into the same cylinder. When transferring water samples after collection, the entire structure needs to be disassembled, which is cumbersome and inefficient, and cannot quickly transfer water samples. In addition, after the water sample is taken out, it needs to be reassembled for the next water sample collection. Summary of the Invention
[0005] To address the above problems, the present invention provides a water collection device for water treatment, which effectively solves the problems pointed out in the background art.
[0006] The technical solution adopted in this invention is:
[0007] A water collection device for water treatment includes a suspension rope with a lifting ring at its lower end. A first sealing tube is fixedly connected to the bottom of the lifting ring, and a second sealing tube is detachably connected to the lower end of the first sealing tube. A fixing seat is provided at the top of the interior of the first sealing tube, and an installation groove is formed in the inner wall of the fixing seat. An elastic balloon is fitted into the installation groove, and a suction bend is integrally connected to the side wall of the balloon. The outer end of the suction bend extends out of the first sealing tube through an opening in the side wall of the first sealing tube. A sealing cap is fitted at the top of the second sealing tube, and the center of the sealing cap passes through the push rod shaft of an electric push rod. The electric push rod is fixed to the upper end of a mounting partition, and the mounting partition is fitted into the inner cavity of the second sealing tube. A storage battery is fixed below the mounting partition. The storage battery supplies power to the electric push rod and all electrical components. Conventional control methods are sufficient and will not be described in detail. A squeezing block is provided at the top of the push rod shaft of the electric push rod, and the squeezing block is vertically aligned with the balloon.
[0008] Preferably, the lifting ring is welded and fixed to the first sealing tube, the bottom end of the first sealing tube is provided with an external threaded ring, and the upper end of the second sealing tube is provided with an internal thread that matches the external threaded ring. The first sealing tube and the second sealing tube are threadedly connected.
[0009] Preferably, the outer edge of the mounting partition is provided with external threads, which are threaded to the wall of the second sealing tube; the battery and the electric push rod are respectively fixed to the lower and upper sides of the mounting partition by bolts.
[0010] Preferably, the outer ring of the sealing cover is provided with an annular sealing ring, and a mechanical seal structure is provided between the central through hole of the sealing cover and the telescopic shaft of the electric push rod.
[0011] Preferably, the extrusion block has a hemispherical structure, the balloon and the suction bend are integrally formed, the balloon is a high-elasticity silicone collection balloon, the suction bend is Z-shaped, all corners are arc transitions, and a sealing gasket is fitted at the contact position between the suction bend and the opening of the first sealing tube.
[0012] Preferably, a plurality of through screw holes are arrayed on the surface of the mounting plate, and the power supply cable of the battery passes through the screw holes and is electrically connected to the electric push rod.
[0013] The beneficial effects of this invention are:
[0014] I. The threaded, split-type double-cylinder structure significantly improves sampling efficiency and facilitates water sample transfer.
[0015] 1. The water sampling unit and the power unit are physically separated, allowing for quick disassembly and replacement.
[0016] This invention achieves detachable assembly by using a threaded connection between the first sealing tube (containing a built-in balloon and a suction bend) carrying the water sample and the second sealing tube equipped with an electric push rod and a battery. After a single sampling is completed and the equipment is pulled out of the water, only the two sections of the sealing tube threads need to be unscrewed to remove the first sealing tube containing the complete water sample, which can then be directly transferred for testing. There is no need to disassemble the electric and power supply components; simply replacing the first sealing tube with a brand-new pre-installed balloon allows for immediate commencement of the next round of water sample collection. This solves the pain points of traditional integrated equipment, which involves cumbersome disassembly and reassembly of the entire machine after sampling and long waiting times for continuous sampling.
[0017] 2. Water samples are isolated from electrical components, reducing the risk of equipment failure and water contamination.
[0018] Water samples are stored only in the balloon of the first sealed tube in the upper section, while the second sealed tube in the lower section encloses the battery and electric push rod. Water and leaked water samples will not come into contact with the power supply and drive components. Even if the balloon is damaged and leaks water, it will only contaminate the upper cavity and will not cause short circuits in the battery or corrosion of the push rod, thus extending the overall service life of the equipment and reducing maintenance and replacement costs.
[0019] II. Electric and electrically controlled squeezing water sampling eliminates manual operation and provides greater controllability in sampling.
[0020] 1. Fully automated negative pressure sampling, requiring no manual underwater intervention.
[0021] Unlike traditional manually squeezed airbags and counterweight sinking cylinder water samplers, this invention relies on a battery to power an electric push rod. The entire process of squeezing out air from the airbag and rebounding to draw water under negative pressure can be completed by remotely controlling the extension and retraction of the push rod. No personnel need to go into the water or manually press the airbag underwater. It is suitable for working conditions that are difficult to operate manually, such as deep water, narrow and closed water treatment pools, and long-distance lowering.
[0022] 2. The squeezing pressure and water absorption are controllable, and the sampling consistency is high.
[0023] The electric push rod stroke can be precisely adjusted, and the hemispherical extrusion block uniformly and flexibly extrudes the elastic balloon, with stable and controllable extrusion force, avoiding the problem of large differences in water volume per operation due to uneven force during manual operation; the hemispherical buffer structure will not scratch or puncture the silicone balloon, reducing consumable consumption.
[0024] III. The equipment is small and lightweight, with no restrictions on additional equipment for on-site layout.
[0025] The existing comparative patent CN211179121U sampling device requires a ground telescopic frame and a rope-driven mechanism, resulting in a large overall size and limited space. The present invention can be lowered into the water body using only a rope, without the need for an external frame or auxiliary lifting equipment. It has a compact and lightweight structure, making it easy to transport and deploy on site. It is suitable for sampling in various scenarios such as small sewage tanks, rivers, deep wells, and various narrow water treatment structures.
[0026] IV. Multiple sealing structures provide excellent waterproof performance and ensure the purity of water samples.
[0027] 1. Multiple layers of sealing prevent external water from seeping in.
[0028] A sealing ring can be added to the threaded mating surfaces of the first and second sealing pipes; an annular sealing ring is configured on the outer ring of the sealing cover; a mechanical seal is set between the sealing cover and the telescopic shaft of the electric push rod to prevent water from seeping into the lower electrical chamber along the push rod gap; a sealing gasket is fitted at the contact position between the liquid suction bend and the opening on the side wall of the first sealing pipe to prevent pool water from entering the cylinder along the gap in the pipe wall.
[0029] 2. The pipeline has no dead corners, is not easy to clog, and does not retain sewage.
[0030] The suction bend adopts an integral Z-shaped design with a full arc corner, eliminating right-angle dead corners and preventing sewage impurities from accumulating and clogging the pipeline. The balloon and suction bend are integrally molded without splicing gaps, avoiding the accumulation of dirt in gaps and causing cross-contamination of water samples before and after, ensuring accurate and reliable water quality test data.
[0031] V. Modular internal assembly, making inspection and maintenance simple and convenient.
[0032] 1. Each functional component is independently bolted and can be disassembled and repaired separately.
[0033] The outer edge of the mounting plate can be detachably assembled into the second sealing tube via threads. The battery and electric push rod are fixed to the upper and lower sides of the mounting plate with bolts, respectively. If the push rod or battery power supply fails, the electrical components can be disassembled and repaired separately by simply unscrewing the mounting plate, without scrapping the entire set of equipment. If the balloon or pipeline is blocked or damaged, only the upper first sealing tube assembly needs to be replaced, resulting in lower maintenance costs.
[0034] 2. Cables should be neatly stored to avoid interference during movement.
[0035] Through screw holes are arrayed on the surface of the mounting plate. The battery power supply cable passes through the screw holes and connects to the electric push rod. Excess wires can be tied and fixed at the screw holes to prevent the cables from getting tangled in the push rod telescopic structure, avoiding jamming and short circuit failures, and making the equipment more stable in operation.
[0036] VI. The structure is universal and easy to process, suitable for mass production in various industries.
[0037] All standard components of this invention can be purchased commercially, while irregularly shaped parts such as balloons, sealing tubes, and bends can be customized according to different sampling water depths and water volume requirements. Each part adopts mature and conventional connection methods such as welding, bolts, and threads, and the circuit uses a low-voltage DC conventional wiring scheme. The processing and assembly threshold is low, which facilitates the mass promotion and use in the water treatment monitoring industry. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0043] Example 1
[0044] like Figure 1-4 As shown, a water treatment collection device includes a suspension rope 1, with a lifting ring 4 connected to the lower end of the rope 1. A first sealing tube 2 is fixedly connected to the bottom of the lifting ring 4. A second sealing tube 3 is detachably connected to the lower end of the first sealing tube 2. A fixing seat 5 is provided at the top of the inside of the first sealing tube 2. An installation groove 6 is formed in the inner wall of the fixing seat 5. An elastic balloon 7 is fitted into the installation groove 6. The side wall of the balloon 7 is integrally connected to a suction bend 8. The outer end of the suction bend 8 extends through an opening in the side wall of the first sealing tube 2 to the outside of the first sealing tube 2. The bottom of the first sealing tube 2 is open, and the top opening of the second sealing tube 3 is fitted with a tight seal. A sealing cap 9 is provided, with the center of the sealing cap 9 penetrating the push rod shaft of the electric push rod 10; the electric push rod 10 is fixed to the upper end of the mounting partition 12, which is assembled into the inner cavity of the second sealing tube 3; a storage battery 14 is fixed below the mounting partition 12, which supplies power to the electric push rod 10 and all electrical components, using conventional control methods, and will not be described in detail. A compression block 11 is provided at the top of the push rod shaft of the electric push rod 10, which is vertically facing the balloon 7, and extends from the bottom opening of the first sealing tube 2 to compress the balloon 7.
[0045] The lifting ring 4 is welded and fixed to the first sealing tube 2. The bottom end of the first sealing tube 2 is provided with an external threaded ring, and the upper end of the second sealing tube 3 is provided with an internal thread that matches the external threaded ring. The first sealing tube 2 and the second sealing tube 3 are threadedly connected.
[0046] The outer edge of the mounting partition 12 is provided with external threads, which are threaded to the cylinder wall of the second sealing tube 3; the battery 14 and the electric push rod 10 are respectively fixed to the lower and upper sides of the mounting partition 12 by bolts.
[0047] The outer ring of the sealing cover 9 is provided with an annular sealing ring, and a mechanical seal structure is provided between the central through hole of the sealing cover 9 and the telescopic shaft of the electric push rod 10.
[0048] The compression block 11 has a hemispherical structure. The balloon 7 and the suction bend 8 are integrally formed. The balloon 7 is a high-elasticity silicone collection balloon. The suction bend 8 is Z-shaped with all corners being arc transitions. A sealing gasket is fitted at the contact position between the suction bend 8 and the opening of the first sealing tube 2.
[0049] The mounting plate 12 has several through screw holes 13 arranged in an array on its surface. The power supply cable of the battery 14 passes through the screw holes 13 and is electrically connected to the electric push rod 10.
[0050] This invention relies on a split-type double-sealed pipe thread assembly structure and an electric push rod to drive the reciprocating motion of the extrusion block. Combined with the deformation of an elastic balloon to generate negative pressure, it automatically collects water samples. The overall operation is divided into five stages: equipment assembly, underwater deployment, electrically controlled water collection, water sample disassembly and replacement, and component maintenance. The specific principles are as follows:
[0051] I. Equipment Assembly Sealing Principle
[0052] 1. Power unit pre-installation: Fix the battery and electric push rod to the upper and lower surfaces of the mounting partition with bolts. The battery power supply cable passes through the through screw holes distributed in the partition array and connects to the electric push rod. Tie the excess cable neatly at the screw holes. Screw the mounting partition with the electrical components into the inner cavity of the second sealing tube through the external thread on the outer edge. Fasten the sealing cover with an annular sealing ring at the upper end of the second sealing tube. The push rod shaft of the electric push rod passes through the central through hole of the sealing cover. The through hole and the push rod shaft are isolated from water by mechanical seal. Finally, assemble a hemispherical extrusion block at the top of the push rod.
[0053] 2. Pre-assembly of sampling unit: The one-piece molded silicone balloon and the Z-shaped arc-shaped liquid suction bend are installed into the first sealing tube. The balloon is inserted into the mounting groove of the top fixing seat. The outer end of the liquid suction bend protrudes through the opening on the side wall of the first sealing tube. A sealing gasket is fitted between the opening and the bend to prevent water leakage.
[0054] 3. Assembly of the whole machine: Align the external threaded ring at the bottom of the first sealing tube with the internal thread at the top of the second sealing tube and tighten it. A sealing ring can be added to the threaded mating surface of the two sealing tubes to achieve overall waterproof sealing. The lifting rope is tied to the lifting ring, and the lifting ring is welded to the first sealing tube to complete the assembly of the whole machine. After the assembly is completed, the extrusion block is aligned vertically upward with the balloon to form an extrusion mating structure.
[0055] II. Underwater Deployment and Positioning Principle
[0056] Holding a rope, the assembled equipment is vertically lowered to the target water depth position in water treatment ponds, rivers, deep wells, etc. The equipment is suspended only by the rope, without the need for external telescopic frames or lifting auxiliary mechanisms. It falls naturally to the designated sampling point by its own weight, thus achieving fixed-point water sample collection.
[0057] III. Core Principle of Negative Pressure Automatic Water Suction Sampling
[0058] The battery continuously supplies power to the electric actuator, which is controlled by an external conventional controller to perform reciprocating motion. Water is drawn in by the pressure difference generated by the deformation of the balloon.
[0059] 1. Compression and degassing stage: The controller outputs a signal to drive the electric push rod to extend. The hemispherical compression block at the top of the push rod presses upward against the elastic silicone balloon. The balloon is compressed and deforms, and the original air inside the balloon is discharged outward along the Z-shaped liquid suction bend, reducing the air pressure inside the balloon. The hemispherical compression block flexibly contacts the balloon without puncturing the elastic balloon, and the compression force is precisely controlled by the push rod stroke.
[0060] 2. Rebound and Water Absorption Stage: After a set delay time, the controller controls the electric push rod to retract, the squeezing block moves downward and detaches from the balloon, and the silicone balloon quickly rebounds and recovers due to its own elasticity. The internal space of the balloon expands to form a negative pressure. The atmospheric pressure outside the water body is greater than the negative pressure inside the balloon, and the water sample in the pool will be continuously drawn into the balloon along the suction bend and stored inside, completing a single water sample collection.
[0061] 3. Pipeline anti-contamination principle: All corners of the suction bend are rounded, with no right-angle dead corners, making it difficult for sewage impurities to accumulate and clog the pipeline; the balloon and suction bend are integrally molded without splicing gaps, avoiding cross-contamination of different batches of water samples caused by residual sewage.
[0062] IV. Principles of Water Sample Splitting and Continuous Sampling
[0063] After water sampling is completed, the lifting rope is used to remove the entire equipment from the water; the threaded connection between the first and second sealing tubes is unscrewed, and the two sealing tubes are quickly separated.
[0064] 1. The first sealing tube in the upper section is an independent water sample storage unit. The internal balloon contains the collected water sample, which can be directly removed and transported to the laboratory for testing.
[0065] 2. The second sealing tube in the lower section is an independent power supply unit. The internal battery, electric push rod and water sample are completely isolated from each other and are not contaminated by water leakage. The brand-new first sealing tube, which is pre-loaded with balloon and suction bend, is re-threaded and connected to the second sealing tube. It can be lowered immediately to carry out the next round of water sample collection without disassembling and repairing electrical components, which greatly shortens the continuous sampling interval.
[0066] V. Principles of Disassembling and Repairing Faulty Components
[0067] When balloon rupture or pipeline blockage occurs, only the first sealing tube sampling assembly needs to be replaced. If the electric push rod is stuck or the battery power supply is abnormal, after unscrewing the two sealing tube threads to separate them, the installation partition inside the second sealing tube can be unscrewed as a whole, and the battery and electric push rod can be disassembled, replaced or repaired separately without scrapping the entire set of equipment. The sealing cap and the sealing gaskets of each pipeline can be disassembled and replaced separately. The entire process is modular disassembly and assembly, and the maintenance operation is simple.
[0068] VI. Multi-layer waterproof sealing auxiliary principle
[0069] The equipment is equipped with multiple sealing structures to prevent water infiltration: seals are installed at the threaded mating surfaces of the two sealing pipes, the outer ring of the sealing cap, between the sealing cap and the telescopic shaft of the push rod, and at the opening of the suction bend and the first sealing pipe; even if the balloon ruptures and leaks water, the water will only remain inside the upper first sealing pipe and will not seep into the electrical compartment of the lower second sealing pipe, thus avoiding battery short circuits and corrosion damage to the electric push rod, and ensuring the stable operation of the equipment in underwater operations for a long time.
[0070] Finally, it should be noted that the above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this invention should be considered within the scope of protection of this invention.
